Title: Ph glass electrode
Inventor: OGO KATSUYUKI
IPC: G01N27/36
Filed: 1985-01-25
Abstract: PURPOSE:To prevent substantially the evaporation of an internal electrolyte by using a solvent of which the vapor pressure at the service temp. of a pH sensitive glass electrode is substantially lower than the vapor pressure of water as a solvent for the internal electrolyte in said electrode. CONSTITUTION:The evaporation of the internal electrolyte of the pH glass electrode can be prevented simply by using the electrolyte which is extremely hardly evaporatable. Such electrolyte is obtd. by using the solvent of which the vapor pressure at the service temp. of the electrode is extremely lower than the vapor pressure of water at the same temp., for example, an org. solvent or liquid polymer having a high b.p. However, these solvents are required to satisfy the following conditions; the solvent is liquid and does not deteriorate at the service temp. of the electrode; the solvent can dissolve various electrolytes, and above all, the electrolyte exhibiting a buffer effect and the solvent can maintain the electrical conductivity and pH stability necessary as the internal electrolyte of the pH electrode. More specifically, polyethylene glycol and PVA are used.

Title: Hand-free telephone set
Inventor: IWATA YOSHIHIRO
IPC: H04M1/60
Filed: 1988-01-25
Abstract: PURPOSE:To effectively prevent a howling generated due to the turn-in of aline to be used by shifting the frequency of a received sound signal by means of a modulating circuit and attenuating it by means of the filter. CONSTITUTION:When a received signal (x) of a frequency omega2 is inputted to a modulator 3, the modulator 3 modulates the received signal by the signal of a frequency omega1 from a transmitter 4. As a result, from the modulator 3, the signals of omega1, omega1+omega2 and omega1-omega2 are outputted. A high-pass filter outputs only the signal of omega1+omega2 to a modulator 6. Thus, the modulator 6 modulates the inputted signal of omega1+omega2 by the signal of frequency omega1+DELTAomega from a transmitter 7, namely, by omega1+DELTAomega. As a result, from the modulator 6, the signals of 2omega1+DELTAomega, 2omega1+DELTAomega-omega2 and omega2+DELTAomega are outputted. Thus, a low-pass filter outputs only the signal of omega2+DELTAomega, simultaneously, the signal of omega2+deltaDELTA is amplified by an amplifier 9, and it is made loud by a loudspeaker 10.
